Influence of nitrogen fertilization management on the bread making quality of different wheat genotypes

Creator:

Derényi, Marina Castro

Abstract:

Breadmaking quality is an important criterion in breeding and development of hard wheat (Triticum aestivum L.) cultivars. Improvements in N management are needed to produce superior quality grain and satisfy market demands for protein content. Field experiments with three hard red and two hard white spring wheat cultivars were conducted...

Long-term effects of tillage, nitrogen, and rainfall on winter wheat yields

Creator:

Camara, Kelli Marie

Abstract:

Winter wheat is commonly grown in dryland cropping systems in the Pacific Northwest region of semi-arid eastern Oregon. For agronomic, economic, and environmental reasons, it is important to understand the long-term sustainability of such dryland systems. The objective of this study was to evaluate the long-term effects of tillage, nitrogen...
